At least as bright as the Sun, if not brighter. Wouldn't want to be outside while that thing is above the horizon!
By the way, I don't want to sound like a language Nazi, but I see the phrase "close proximity" a lot. Is there such a thing as "distant proximity"? "Close proximity" is a bit redundant, sort of like "good progress". (Is there such a thing as bad progress?)
